This worksheet is for custom poly shipping bags, poly bubble mailers and metallic bubble mailers. Compare each offered construction separately: an unpadded shipping bag and a bubble-lined bag are different specifications, even when their quoted outer dimensions match.
What Should I Include When Requesting a Custom Shipping Bag Quote?
Identify the exact mailer format and state whether your dimensions are outer or usable inner dimensions. Include the packed product, quantity per size and design, artwork, intended finish, sample needs and destination. Use consistent units and mark requirements that are still open.
The 500-piece quotation checklist helps you prepare the initial enquiry. This comparison worksheet is for the next step: checking whether the replies describe the same order.
What Should I Compare in Poly or Bubble Mailer Quotes Before Price?
Copy the written terms from each quotation into this worksheet. “To confirm” marks an unanswered field; it is not a supplier offer or a price estimate.
Swipe the table horizontally to see Quote B and the questions.
| Field | Quote A | Quote B | Question to resolve |
|---|---|---|---|
| Mailer type and construction | To confirm | To confirm | Are the offered structures the same? |
| Outer and usable dimensions | To confirm | To confirm | Are units, flap allowance and measurement directions clear? |
| Material and thickness | To confirm | To confirm | What exactly is included in the measurement? |
| Artwork and print sides | To confirm | To confirm | Are colors, coverage, placement and printing method included? |
| Quantity per size/design | To confirm | To confirm | Does the minimum apply to each configuration? |
| Sample route | To confirm | To confirm | Stock sample, artwork proof or custom printed sample? |
| Production start milestone | To confirm | To confirm | Which approvals or payments start the schedule? |
| Delivery scope | To confirm | To confirm | Which destination, service and charges are included? |
For a bubble mailer, confirm usable inner space after accounting for the lining. For a printed poly mailer, confirm print sides and the offered method. For a metallic mailer, identify the exact surface effect. Compare the three mailer formats if the construction is still undecided.
Separate the Cost Items
- Products: unit price, quantity per size/design, currency and the total product amount.
- Setup: any separately quoted artwork, plate or tooling charges, and whether they apply again on a repeat order.
- Samples: the sample type, any quoted preparation charge and the courier arrangement.
- Packing and delivery: carton requirements, freight, destination and other stated charges.
- Unresolved items: identify charges still awaiting confirmation before comparing totals.
If destinations or delivery terms differ, resolve those differences first. Ask which freight and destination charges are included, excluded or estimated. Keep the quoted terms beside your comparison so the total can be checked.
Compare Timing by Milestone
Keep design, sample preparation, sample transit, production and bulk transit as separate stages. Record the event that starts each stage. An estimate measured from artwork approval has a different starting point from one measured from payment or dispatch.
At Welltroy, the initial design draft target is within 24 hours after a clear brief. Samples are free. Preparation can take as little as 3 days after specifications and artwork are confirmed. The delivery target is within 7 days of confirmation, depending on destination. Confirm the sample type and shipping arrangements, including any delivery charges, before dispatch.
Bulk production: Typically about 15–20 days after payment. Confirm the production start milestone in your quotation; shipping time is additional.
Confirm your required arrival date and destination with the supplier. See samples, payment and delivery terms for the current Welltroy process.
Resolve Exceptions Before Approval
Ask for a revised written quotation when you change size, artwork, material, quantity or delivery scope. Keep the final specification, sample approval record and quotation together, with a version and date for each.
Eligible Welltroy specifications start from 500 pieces; confirm the minimum for each size and design. To request a comparison-ready proposal, send the same specification and destination through our enquiry form.
